1. Field of the Invention
The present invention relates to a cargo securing device, and particularly to a cargo securing device allowing for multiple horizontal and vertical securing points.
2. Description of the Related Art
Individual movers, truck drivers and others frequently use cargo-fastening devices to stabilize the load so that assorted cargo may be safely hauled aboard various vehicles. The cargo often includes items that are of different sizes and heights. The items to be hauled, for example, may be simple crates or cumbersome and unwieldy furniture. It is necessary to confine the hauled items such that they do not slide about the vehicle or truck bed and thus become damaged. In order to secure the cargo, a variety of restraining devices are used, including ropes, elastic cords, wires, etc. The restraining devices are attached to truck bed walls or floors by anchors, hooks, and the like.
While effective to an extent, these restraining devices are limited to a certain number of anchoring points about the truck bed. The anchoring points are often restricted to four securing points, generally two in the front and two in the back. Some improvements provide an additional two anchoring points in the middle of the truck bed. However, six anchoring points may not be enough to effectively restrain certain types of cargo. In some instances, a greater number of securing points would be beneficial to the cargo hauler.
Additionally, a variety of securing mechanisms provide anchoring points along the same plane, such as along the truck bed or along a track attached about the sides of the truck bed. However, these mechanisms do not allow for multiple anchoring points along different planes, such that different types of hauled goods may be more easily accommodated.
Accordingly, there is a need for a simply constructed cargo securing mechanism that provides multiple fastening points. The greatest benefit to a cargo mover would be from a securing device that permits the securing of cargo at any point around the cargo area. Further, there is a need for a cargo securing mechanism that may be adjusted to varying heights to permit a greater range of anchoring points.
U.S. Pat. App. Pub. No. US 2002/0048495 A1, published Apr. 25, 2002 and invented by M. Anderson et al., describes a cargo bed tie-down system. Tie-down tracks are extended within the body of a truck and on the truck bed. The tracks do not extend beyond the adjoining truck body and are therefore more easily able to blend into the body of the truck.
U.S. Pat. No. 4,850,769, issued Jul. 25, 1989 to J. Matthews, describes a tie-down device for a pickup truck. The device has a movable car with a fastener that is slidably mounted on a track. The track is situated about the perimeter of the truck body and additional tracks may be situated on the truck bed. The car with the fastener attached may be moved along the track and used as an anchoring mechanism for any number of positions on the track.
U.S. Pat. No. 5,533,848, issued Jul. 9, 1996 to O. Davis, describes a payload tie-down system. The system consists of tracks placed about the perimeter of the truck body and along the truck bed. S-shaped hooks are attached to carriages that are slidable onto the tracks. The S-shaped hooks connect to ropes or other securing means to hold down cargo.
U.S. Pat. No. 4,396,324, issued Aug. 2, 1983 to R. Ellis describes a tie-down apparatus that is positioned along the side walls of a pick-up truck. Rails are extended between stake walls and engage holders positioned against the stake walls. The holders each have a coupling socket into which the rails are extended.
U.S. Pat. No. 4,936,724, issued Jun. 26, 1990 to V. Dutton describes a truck box top molding. Slotted rails are attached along the perimeter of the top of the truck box. The rails are fastened by screws extending within the truck box. The slots in the rails allow a rope, wire or the like to attach onto the truck box.
U.S. Pat. No. 5,040,934, issued Aug. 20, 1991 to K. Ross describes a cargo retaining device comprising a net made of crisscrossing material and a cord. The cord is secured to the net by knots and attached to the cargo-hauling vehicle. The device allows the net to cover and secure the cargo within the vehicle bed.
U.S. Pat. No. 6,077,007, issued Jun. 20, 2000 to E. Porter et al. relates to a pick-up truck bed organizer and method. The organizer fits within the bed of a truck and is comprised of multiple legs, which are connected to each other with connectors. The connectors each have tubular plugs to which the legs telescopingly connect. The legs and connectors may be rearranged to allow for varying sizes and types of cargo to fit within the truck bed.
U.S. Pat. No. 6,149,361, issued Nov. 21, 2000 to D. Schrader describes a securement device for securing cargo within a truck. The device consists of a hollow member attached about the top perimeter of a truck box and an additional hollow member attached at a higher level about the perimeter of the truck box. Cords for securing cargo are fastened within the hollow member and are slidable along the hollow member.

None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Thus a device to secure cargo solving the aforementioned problems is desired.
The invention is a cargo securing device for restraining cargo within a vehicle. A chain assembly extends about the entire perimeter of a cargo area of a vehicle, and is attached to spaced locations along the cargo area sidewalls. Alternatively, the chain assembly may be attached to the cargo area floor. Once the chain assembly, made up of a number of links, is secured to the cargo area sidewalls, restrainers such as straps, hooks or other fasteners may be attached onto any link in the chain assembly. The restrainers are used to restrain cargo stored within the cargo area. Generally the chain assembly is fixed to the cargo area sidewalls at four points such that the chain assembly is formed into a rectangular shape. However, the chain assembly may be fixed to the sidewalls at additional points according to the preferences of the user.
In an additional embodiment, brackets are joined onto the chain assembly at various points, but generally at four points such that the chain assembly is formed into a rectangular shape. The brackets are attached to the cargo area sidewalls, securing the chain assembly to the sidewalls. The brackets are either welded or bolted to the walls. The brackets may be affixed to the wall by sliding the brackets to holding latches already affixed to the cargo area sidewalls.
Additionally, telescoping units are used with the cargo securing device to heighten or lower portions of the chain assembly, allowing the restrainers to restrain the cargo on different levels. Each telescoping unit has a rod and a hollow shaft into which the rod is inserted. The telescoping units generally are affixed to the sidewalls at four corners of the cargo area. The telescoping units are either welded directly onto the sidewalls or welded or bolted to the brackets that are secured to the cargo area walls.
The chain assembly is attached to the bottoms of the telescoping units with fasteners, such as hooks. An additional chain assembly is attached to the tops of the telescoping units with fasteners. The additional chain assembly runs from the top of each telescoping unit to the top of the next telescoping unit. The telescoping units may then be raised or lowered according to the height of the cargo, thus allowing the chain assemblies to surround the cargo at different heights. The chain assemblies may be a single chain structure about the tops of the telescoping units and descended downwardly to be attached at the bottoms of the telescoping units.
Portions of the chain assembly may be shortened or lengthened. The portions of the chain assembly are adjusted by relooping the chain assembly through the brackets. In addition, certain brackets through which the chain assembly may be extended allow the chain assembly to be shortened or lengthened by adding or removing slack in the chain.
One aspect of the invention is that the cargo securing device provides for multiple attachment points to which the restrainers are linked. The multiple attachment points provide for better safety in retaining the cargo by preventing stray cargo pieces from falling off the cargo vehicle. Another aspect is that the cargo securing device may have multiple levels such that retainers may restrain the cargo at different heights. A further aspect of the invention is that the cargo securing device does not materially alter the existing layout of the cargo bed.
It is an aspect of the invention to provide improved elements and arrangements thereof for the purposes described which is inexpensive, dependable and fully effective in accomplishing its intended purposes.
These and other aspects of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
The present invention is a cargo securing device 10 for restraining cargo. The device 10 is made up of a chain assembly 12 extended around a perimeter of a cargo area of a vehicle and several brackets 16 connected to the chain assembly 12. The brackets 16 are attached to the sidewalls 20 of the vehicle such that the chain assembly 12 is affixed to the sidewalls 20. Restrainers 30 latch onto the chain assembly 12, and wrap about cargo 40, securing the cargo 40 in place. Alternatively, the brackets 16 could be welded or bolted to the cargo bed sidewalls, or slid into holding latches affixed to the sidewalls (not shown).
Referring first to
Additional brackets 16 may be added to the chain assembly 12 to allow additional fastening points for the restrainers 30. A portion of the chain assembly 12 may be extended down the center of the cargo bed so that the cargo bed may be divided into sections to better retain certain types of cargo. Other anchoring devices, such as snap links, may be used in substitution for the brackets 16.
Turning now to
In another embodiment, the cargo securing device 10 may be attached directly to the cargo area sidewalls 20. The brackets 16 are omitted, and the chain assembly 12 is welded or affixed in another manner onto the sidewalls 20.
Turning now to
Restrainers 30 are latched onto the links 14 or 18 of the chain assembly 12. Additional telescoping units 50 may be added to allow restrainers 30 to attach to more points on the chain assembly 12. The telescoping units 50 are attached to the brackets 16, which are secured to the sidewalls 20, by welding or bolting the units 50 to the brackets 16. The telescoping units 50 may additionally be welded or bolted directly onto the cargo area sidewalls 20. The telescoping rods 52 of the telescoping units 50 may be raised or lowered according to the needs of the user.
A section of the chain assembly 12 may be shortened by relooping a portion of the chain assembly 12 to one of the brackets 16, as shown in
Additionally, a section of the chain assembly 12 between two of the brackets 16 may be detached to allow for longer cargo 40 to be situated without the impediment of the chain assembly 12.
The cargo securing device 10 may be attached to a vertical surface, such as a sidewall, or a horizontal surface, such as a cargo floor.
A locking mechanism (not shown)may be affixed to one of the brackets 16 of the cargo securing device 10 in order to lock the cargo securing device 10 to prevent theft.
